Removal & Installation
- Remove the nut, washer and bushing from the upper end of the shock absorber.
- Raise and safely support the vehicle by the frame rails allowing the front wheels to hang.
- Remove the 2 bolts securing the shock absorber to the lower control arm and remove the shock absorber.
- Before installation, purge a new shock of air by repeatedly extending it in its normal position and compressing it while inverted.
- Install a new bushing and washer on the top of the shock absorber and position the unit inside the front spring. Install the two lower attaching bolts and torque them to 13-16 ft. lbs. (17-23 Nm).
- Lower the vehicle.
- Place a new bushing and washer on the shock absorber top stud and install a new attaching nut. Tighten to 26 ft. lbs. (41 Nm).
Testing & Inspection
- Remove the shock absorber from the vehicle.
- Extend the shock absorber fully while it is right side up, as installed in the vehicle. Then turn it upside down and fully compress it. Repeat this procedure at least 3 times to make sure any trapped air has been expelled.
- Place the shock absorber right side up in a vise and hand stroke the shock absorber. Check the shock absorber insulators for damage and wear.
- If the shock absorber is properly primed, in its installed position, and there is a lag or a skip occurring near mid-stroke of the shaft reverse travel direction, the shock absorber must be replaced.
- Replace the shock absorber if there is any seizing during the shaft full travel, except at either end of the travel.
- Replace the shock absorber if upon the shaft fast, reverse stroke, there is any noise encountered other than a faint swish, such as a clicking sound.
- If there are excessive fluid leaks, and the shock absorber action remains erratic after purging air, replace the shock absorber.
